MCP Shield

An open-source security scanner for Model Context Protocol (MCP) servers that checks for vulnerabilities such as SSRF, path traversal, injection, and authentication flaws. It provides a grade from A to F, maps findings to CWE IDs, and offers actionable remediation steps. It can run as a CLI tool or integrate directly into Claude Code via MCP.
